As a freshman, Harrison, 20, was part of a BYU team that advanced to the third round of the 2012 NCAA Tournament, but a mix-up over when he would take a mission trip for the LDS Church led to his exit from Provo, Utah, according to KSL.com.

When Harrison will play is unclear because Clemson has said it plans to file a waiver in an attempt to allow Harrison to play this season. NCAA rules state a player must typically sit out a year when transferring from Division I program to another.

Harrison had been planning since at least the spring on taking his two-year Mormon mission beginning this summer, and BYU consequently had committed all 13 of its scholarships before Harrison’s mission was delayed.

"I made some phone calls and found out they didn't have an available scholarship,” Harrison told KSL.com. “I thought they (BYU) might be able to do something, but it just didn't work out.”

Clemson, meanwhile, is looking for help at guard. Tanner Smith and Andre Young are gone from last season’s team.

“We’re excited to add Damarcus to our program,” coach Brad Brownell said, according to the Post & Courier. “He’s an athletic wing with a good skill set, and will certainly provide our team with much needed depth at his position.”

Harrison told KSL.com that approval of the NCAA waiver would be a "best-case scenario," making him eligible to contribute immediately. Asked if he thinks there's a good chance of the waiver being approved, Harrison said, "I think so."

Clemson was one of the schools that offered Harrison a scholarship out of high school, along with South Carolina, Charleston, Marquette and others, the Salt Lake Tribune reported, adding that BYU coaches logged thousands of miles of air travel recruiting the prep phenom who played two seasons at Greenwood High before transferring to play at Christ School in Arden, N.C., from 2009-11.

BYU coach Dave Rose once said his staff probably spent more time trying to lure Harrison to Provo than any other player in his tenure, the Tribune noted.

Harrison appeared in 30 games for BYU as a freshman, averaging 3.2 points and 1.0 rebounds a game. He averaged just 8.8 minutes a game, and went through several stretches during which he never got off the bench.

Oddly, the Tribune noted, his best game for BYU was his second-to-last, when he scored a career-high 12 points on 4-for-6 shooting in a 78-72 comeback victory over Iona in the first round of the NCAA Tournament.
